Step 5: baseband chip utilizes described liquid crystal display device driving function to this liquid crystal display device initialization, and the chip for driving of operating this liquid crystal display device is correctly controlled the demonstration of this liquid crystal display device;
Step 6: mobile phone shutdown.
When new display device, the interpolation of postponing in the ADC value in described step 1.
In the described step 2 associated drives of liquid crystal display device action comprise initialization, desired location, enter dormancy, go out dormancy, shutdown, contrast control.
Reading in the described step 3 adopted the algorithm that repeatedly is averaged.
When new display device, the interpolation of postponing in the ADC value in described step 1.
In the described step 2 associated drives of liquid crystal display device action comprise initialization, desired location, enter dormancy, go out dormancy, shutdown, contrast control.
Reading in the described step 3 adopted the algorithm that repeatedly is averaged.
The invention has the beneficial effects as follows:
The inventive method can be in conjunction with downloading existing LCD (LCD, Liquid Crystal Display, LCD) driver of IC is in mobile phone, carry out respective calls by the value that reads Different L CD ADC, thereby can discern employed LCD type automatically, control adapts to the demonstration of dissimilar LCD flexibly, to adapt to different display devices, and needn't carry out the download of repeatability again at the different different software of LCD chip for driving compiling, and improved the mobile phone efficiency of research and development greatly, saved cost and time.And, when same mobile phone hardware is changed Different L CD display device, need not to download again software, can realize correct demonstration, make factory produce the frequent updating that can adapt to different display devices in the line production process flexibly.
Description of drawings
Fig. 1 is the frame diagram that mobile phone of the present invention is discerned the method for different display screens automatically.
Fig. 2 is the flow chart of the inventive method.
Fig. 1 comprises PC, and mobile phone, mobile module comprise baseband processing chip and LCD drive circuit again.
Embodiment
The present invention will be further described below in conjunction with drawings and Examples.
The inventive method mutual by with PC and mobile phone side serial ports, read the value of LCD ADC in the start process, automatically judge concrete LCD chip for driving model according to this value position, model is loaded into the LCD driving function of respective type on the corresponding overall situation function pointer in view of the above, so just can discern automatically different LCD chip for driving, need not to repeat compiling, accomplish compatible different LCD display parts.
Fig. 1 is the frame diagram of the method for the different display screens of handset compatibility of the present invention.PC utilizes common Serial Port Line by UART Universal Asynchronous Receiver Transmitter (UART, Universal AsynchronousReceiver/Transmitter) links to each other with mobile phone hardware, this mobile phone uses base band integrated circuit (BBIC), base band integrated circuit and liquid crystal display drive circuit (LCD Driver IC) transmit by parallel 16 bit data bus (D0--D15) and drive order and video data, make normal display action with correct control LCD.
Relate in the present embodiment the LCD situation as follows: the LCD that producer one produces is the LCD driven product for the sharp R61505U (DRIVER IC model) that uses of letter, the LCD that produces with producer two (promptly, be the LCD driven product with the ILI9320 (DRIVER IC model) that uses of SVA, and any LCD that may postpone and add.Realize concrete grammar of the present invention as shown in Figure 2, the concrete grammar step is as follows:
Step 1: be respectively the ADC value scope of setting a standard at all LCD display parts of usefulness by PC, follow-up have an interpolation of can postponing of new display device, and with the driver of the driver that might relate to download to mobile phone:
The LCD of different driving IC need set different ADC values, as, the LCD that producer one produces, promptly letter is sharp uses R61505U (DRIVER IC model) to be LCD driven, can set the ADC value and be 200-230, the LCD that producer two produces, promptly the ILI9320 (DRIVER IC model) that uses of SVA is LCD driven, can set the ADC value and be 230-260, and the like, such ADC value should strictly be controlled the definite of LCD sequence number, otherwise it is chaotic to cause follow-up maintenance and production to take place, table specific as follows:
Table 1 LCD display part sequence number and ADC value correspondence table
| The LCD of producer one | ADC：200-230 |
| The LCD of producer two | ADC：230-260 |
| The LCD of producer three | ADC：260-290 |
The display device of the LCD of producer three for postponing and adding.
All LCD are carried out above ADC to be set.
Simultaneously, having compiled the LCD of producer's one production and the LCD of producer's two productions in advance on PC (has promptly adopted the R61505U (DRIVER IC model) that uses of letter profit to be the LCD driven product, be the LCD driven product with the ILI9320 (DRIVER IC model) that uses of SVA) the driver of drive circuit, and downloaded to mobile phone by the uart mouth
Step 2: baseband chip is dynamically to point to the function pointer of concrete function with the associated drives action unified Definition of LCD, point to the driver of LCD1, LCD2 and LCD3 respectively, this drive actions comprises initialization, desired location, enters dormancy, goes out dormancy, shutdown, contrast control.
Step 3: the mobile phone start that powers on, baseband chip is opened the ADC passage, reads the ADC value of Different L CD, adopts the method for averaging that repeatedly reads in reading process.In the present embodiment, reading times is three times, and for example reading of data is 220,210,230, finally averages 220 to be the ADC value.
Step 4: baseband chip is according to the value of the LCD ADC that reads, promptly 220, in standard sequence number tabulation, mated, judge the type of corresponding LCD, be LCD1, find corresponding liquid crystal display device driving function, the function pointer that defines in the step 2 is pointed to corresponding liquid crystal display part driving function;
Step 5: baseband chip utilizes described liquid crystal display device driving function to this liquid crystal display device initialization, and the chip for driving of operating this liquid crystal display device is correctly controlled the demonstration of this liquid crystal display device;
Step 6: LCD identification, initialization finish mobile phone shutdown.
After above step was finished, mobile phone can correctly show the control of being correlated with to corresponding LCD, thereby had realized the automatic identification of Different L CD display device.Step 1, two is an initialization step, only needs to carry out once, or carry out disposable renewal when having newtype LCD to add.When mobile phone is changed LCD in concrete debug process, only need execution in step three to six just can discern LCD display automatically.
Being preferred embodiment of the present invention only in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should be technology category of the present invention.
